feat(chat-character): 관계 name 필드 추가에 따른 등록/수정/조회 로직 및 DTO 반영

- 관계 스키마를 name, relationShip 구조로 일원화
- Admin/사용자 컨트롤러 조회 응답에서 관계를 객체로 반환하도록 수정
- 등록/수정 요청 DTO에 ChatCharacterRelationshipRequest(name, relationShip) 추가
- 서비스 계층 create/update/add 메소드 시그니처 및 매핑 로직 업데이트
- description 한 줄 소개 사용 전제 하의 관련 사용부 점검(엔티티 컬럼 구성은 기존 유지)
